[Test-Equipment] Anyone with a precision C meter?

[n4buq]

The original standard was a custom-built can rated at 800V and was 
probably good to 0.1% or better.  They don't stock replacements for this 
anymore (built in the'60s?).  That's what I'm trying to duplicate.

To what tolerance can you check it?

Thanks!
